Khan Academy: 3 D Vector Fields, Introduction
Vector fields can also be three-dimensional, though this can be a bit trickier to visualize.
Khan Academy
Khan Academy: 3 D Vector Field Example
See an example of how you can start to understand how the formula for a three-dimensional vector field relates to the way it looks.

Khan Academy: 2 D Curl Intuition
A description of how vector fields relate to fluid rotation, laying the intuition for what the operation of curl represents.
Khan Academy
Khan Academy: 2 D Curl Formula
Here we build up to the formula for computing the two-dimensional curl of a vector field, reasoning through what partial derivative information corresponds to fluid rotation.
